COLEOPTERA OF SOUTHERN CALIFORNIA. 61 



the western border of the Colorado desert, in April. 

 Captain Casey writes me that the type which was sent to 

 him with other specimens for study has been lost. The 

 remaining California!! species with their localities are 

 as follows: Lophioderus gracilis, San Jose; L.myops, San 

 Francisco; Drastophus Icevicollis, San Francisco; Scyd- 

 mcenus sparsus, San Jose; 8. pacificus, San Francisco 

 and north; S. fuchsi, San Francisco; 8. calif ornicus, 

 northern; S. catalinus angustus, San Jose; Cephennium 

 anophthalmicum, San Francisco; Veraphis impressa,. 

 Lake Tahoe; Scydmcenus ovithorax Bndl., Santa Clara 

 County. According to Casey's recent revision, the last- 

 named species would not be a true Scydmcenus, and 

 would perhaps require the erection of a new genus for 

 its reception.
